GEARING.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed September 3, 1913. Serial No. 787,829.

T0 allee/10mi?? may concern Be it known that I, CAMILLE CONTAL, acitizen of the Republic of France, residing at 6 Avenue Magenta, St.Cloud, Seine et Oise, in the Republic of France, have invented certainnew and useful mprovements in Gearing, of which the following is aspecification.

My invention relates to certain improvements in multiplying gearing, andmore particularly to a type adapted to be driven by hand, and movedabout during the operation.

In making my invention, 1 had in mind particularly, vacuum cleanerapparatus, in which the air pump or blower employed for creating thedesired degree of vacuum is driven by hand. My invention is not limitedto vacuum cleaner apparatus, as it may be employed in connection withvarious other forms of apparatus, particularly where it is important tosecure a high degree of speed multiplication, and at the same time keepthe frictional resistance of the working parts as low as possible.

1When employed in a vacuum cleaner apparatus, the pump or blower ispreferably mounted at one end of a tube or helve and adjacent thesuction nose-pipe, while the multiplying gearing and the handle fordriving the same are located at the opposite end of the tube or helve.The two yare connected by a shaft extending lengthwise of thesaid helve,and thus as the shaft is rotated at high speed, it is subjected to onlya comparatively small torsion, and can thus be very lightly constructed.The character of the mechanism driven by the shaft forms no portion ofmy present invention, and it is therefore immaterial whether the helvebe straight, curved, or articulated, or whether the shaftfbe rigid,flexible, or provided with universal joints. r

In some forms, the multiplying gearing may be disposed closely adjacentto the mechanism to be driven so that the main connecting shaft will bes comparatively short.

One specific embodiment of my invention is illustrated in theaccompanying drawings to which reference is to be had, and in whichsimilar reference characters indicate corresponding parts in the severalviews. This specific embodiment as well as the drawings and descriptionthereof, are to be considered in an illustrative sense as vaing adriving mechanism constructed in accordance with my invention, the lowerportion of the apparatus being shown in section. Figs. 1u and 1b showmodied forms of the suctionnose-pipe. Figs. 2 and 3 are axial sectionsof the upper portion of the apparatus. Fig. i is an elevation of thedust collecting bag turned inside out.,

In the drawings, 1 designates a tube constituting the helve of theapparatus and carrying at its lower end a cylindrical casing 2 and atits upper end a hemispheric casing 3; the former inclosing the blower land the latter the speed multiplier. Such multiplier comprises a gearwheel 5 having a crankhandle G, two pinions 7 meshing with such wheel,two frictional disks or plates 14 associated with such pinions and ananti-friction roller 8 secured to the shaft 9 of the blower, which islocated within the tube 1.

rThe wheel 5 is of hemispheric shape corresponding to that of the casing3, to which it serves as a lid; such wheel is mounted on a spindle10'which passes through a socket 11 integral with the casing 3. Both thepinions 7 with which it meshes are located on two spindles 12 secured onthe one hand to the casing 3 and on the other hand to the lateral bossesof the socket 11; they are subjected to the action of springs 13, whichpress the plates 14 onto the opposite sides of the roller 8. The upperpart of the shaft 9 is journaled in a piece 26 which is so guided'inthecasing 3 as to be enabled to slide'freely in a direction parallel tothe axis of the plates 14. By means of such freedom, the roller 8 andthe plates 14 are enabled to move slightly under the iniiuence of the`pressures of the springs 7, so that such pressures are made equalautomatically, as well as the tangential strain on the roller 8, whichavoids any pushing of the shaft 9 on its guide 26a; the friction is thusrendered negligible notwithstanding ythe high speed rotation of theshaft.

`15 designates the arms or braces which hold the socket 11 rigidly inthe casing 3.

A handle 16 is screwed to such casing and forms a prolongation ofthesocket 11; it is preferably hollow, to contain a lubricant.

The blower casing 2 is open at its lower part and receives removably anyone of the.

suction nose-pipes 17, 18 or 19 shown in Figs. l, 1a and 1b; thenose-pipe 17 is upwardly curved and carries a flexible pipe 20terminating in a rigid tube having a sucker cup which can be applied toand moved on the hangings, tapestry, the furniture and y the like; thenose-pipe 18 terminates at the bottom in an elongated sucker cup whichserves to clean the carpets; the nose-pipe 19 has a= narrow sucker cup22 more particularly designed to clean arm-chairs and otherv j pipe 25and is received in a bag 26.

To clean acarpet, for instance, the casing 3 is provided with thenose-pipe 18, and the apparatus is so operated as to apply the suckercupV 21 to the carpet and then to move "the same over the entire surfaceof such carpetwhile turning the blower at the same time; for suchpurpose, the crank-handle 6 will be turned by theright hand and thehandle 16 will: be held by the left hand so as to affordl the requiredsupport; the operator-will bey able to push the apparatus easily forwardby bearing his breast against the plate 2i?, which is mounted on thecasing 3 by' means of a knee-cap joint 28. lf required, the weight ofthe upper part of the apparatus may be transferred in part onto theshoulders of the operator by means of a strap hooked to such upper part;such strap not being shown in the drawings.

` The rotation speed of the handle 6 is multiplied in the first place bythe wheel 5v and` the pinions 7 and a second time by the plates Hand theroller 8, so-that the blower' revolves very quickly with energeticaction.

'i The passive resistances are weak ones, by

dition of ball-bearings.

reason of the simplicity of the controlling means and the peculiar'construction of the speedv multiplier. Such resistances may, moreover,befurther diminished bythe ad.-

Again, the. oiling of all the frictional parts can be easily secured,for instance by means of the lubricant placed in the handle 16 andoiling devices placed. on the bearings ofthe shaft 9.

i Such conditions allow the construction of a very efiicient apparatusand one which works smoothly. Furthermore, the arrangement of all theelements of the' mechanism such as thek gearing, theY shaft. the

` blower, within a tube and casingr forming a compact covering, makesthe hereinbefore` described. cleaning device a self-contained apparatuswhich is proof against outside shocks, does not. get out of order,offers no danger to those persons which use the same andy which is verycompact.

The dust collecting bag 26 has an opening at its upper part, the edgesof which are provided with a metal clasp 29 articulated at 30; Suchopening is normally held closed by means of a clip 31, hanging by achain or wire from the helve 1.

rlhe lower end of the bag is provided with an opening for the passage ofa rigid tube 33 and is secured around such tube by a binding- 34. Theouter part of the said tube isengaged with a little friction in the pipe25'; whileitsinner part, which extends within the bag, is provided witha deliecting cone 35 and a bail 3G which allows the passage of a linger.Such means allow of turning the bag readily inside out to get rid of allthe dirt after having withdrawn the tube 35 from the pipe 25 and openedthe clip 31, the top of the bag is opened and lowered, while the bottoniof the tube 33 is resting on the floor or other support, until the bail36 can be easily caught; the turning of the bag can then be readilyfinished by pulling the bailv upward and the clasp 29 downward (see Fig.4). The deii'ecting cone 35 is not essential.

Tithout departing from the invention one-can, of course, modify theshape of the casings 2 and 3, as well as that of the blower 4 and thedifferent sucker nose-pipes; in the same way, there may be used a speedmultiplier of any suitable construction, comprising if required severalgearings located at different points of the apparatus.
